Also known as
Complete Metabolic Panel, CMP, Chemistry 14, Chem 14, Chemistry Panel, or Chemistry Screen.
What is the Purpose of a Complete Metabolic Panel?
The Comprehensive Metabolic Panel (CMP) is a window into your overall wellness. This group of 14 tests provides an overview of the functioning status of your vital organs and bodily fluids. It evaluates the status of your kidneys, liver, and electrolyte and acid/base balance, as well as your blood sugar and blood proteins.
What Does the CMP Blood Test Measure?
CMP labs measure:
- Blood glucose
- Calcium
- Sodium
- Potassium
- Carbon dioxide
- Chloride
- Albumin
- Total protein in the blood
- Alkaline phosphatase (ALP)
- Alanine transaminase (ALT)
- Aspartate aminotransferase (AST)
- Bilirubin
- Blood urea nitrogen (BUN)
- Creatinine
Only one blood draw is needed to run all 14 tests.
Who Should Take a CMP Test?
Doctors generally recommend a CMP blood test as part of your annual health checkup. The tests are used as a barometer of your well-being, ensuring you are in good health or spotting potential issues early so you can seek effective treatment. A physician may also order a CMP test if you’re on medications that may affect your liver or kidneys. Finally, a CMP can help your doctor diagnose a suspected medical condition.
Comprehensive Metabolic Panel Preparation
Fasting is required for 12 hours before giving your blood sample. You may want to talk with the lab technician about your current medications prior to taking the test in case they influence the results.
Complete Metabolic Panel Results
The Personalabs CMP lab test results are easy to read. Once your test is completed, you will receive a report that shows both the normal “reference range” for the biomarkers that were tested, and how your test results compare to the recommended normal levels.
Abnormal CMP test results could be caused by medications you were taking at the time of the test, whether you ate or drank during the fasting period before the test, and whether you exercised before the test.
If your test results show abnormal biomarker levels, you may want to get tested again to verify whether there is reason for concern.

A Comprehensive Metabolic Panel at Personalabs costs $44 — and that includes your physician-signed lab order. No hidden fees, no insurance required, no doctor’s appointment needed.

Comprehensive Metabolic Panel Frequently Asked Questions
Can I order a CMP blood test without a doctor’s prescription?
Yes — in most states. Personalabs operates through a physician network that provides the lab order on your behalf, so you do not need your own doctor’s referral or prescription to get tested. After you order online, our network physician reviews and approves your order within 2-4 hours. A small number of states have restrictions on direct-to-consumer lab testing; contact us to confirm availability in your state.
What is the difference between a CMP and a BMP?
A Basic Metabolic Panel (BMP) measures 8 markers covering kidney function, blood sugar, and electrolytes. The Comprehensive Metabolic Panel (CMP) includes all 8 BMP markers plus 6 additional liver function tests, making it a more complete picture of your overall metabolic health.
Do I need to fast before a CMP blood test?
Yes. You should fast for 10-12 hours before your CMP blood draw. Water is allowed. Fasting ensures accurate glucose and other metabolic readings.
How long does it take to get CMP results?
Through Personalabs, CMP results are typically available within 24-48 hours of your blood draw in your secure online portal.
What does a high creatinine level on a CMP mean?
High creatinine on a CMP may indicate reduced kidney function or kidney disease. It can also be temporarily elevated due to dehydration, intense exercise, or high protein intake. Consistently elevated creatinine warrants follow-up with a healthcare provider.
What does a high glucose level on a CMP mean?
A high fasting glucose on a CMP may indicate prediabetes or diabetes. A single elevated reading is not a diagnosis — your provider will typically confirm with a follow-up A1c or fasting glucose test. Stress, illness, and certain medications can also temporarily raise glucose levels.
Is the CMP covered by HSA or FSA?
Yes. The Comprehensive Metabolic Panel qualifies as a reimbursable medical expense under HSA and FSA plans.
